No,912,416. Speeificetion of Application filed. Augult 11 for Looms, of which the following iescription, connection with the accompanying is a specification, like characters onthe awing representin like parts.

In automatic looms of tietype wherein the runnin fillingis replenished prior to complete ex austion the shuttle-feeler is geny provided with a deviceto out the old or spent filling'between the clothand the shuttle when filli'n replenishment is efected, the shuttle-teeler bei arranged to prevent replenishment if tie shuttle .is

'nnpro erly boxed. A loom provided with threa parting mechanism of the general type; referred to is shown in United States Patent N 0. 683,423, granted September 24,

1901, to C, H. Draper, the parting device All .--there will e a fault in theQlb U My present invention has being actuated by impingement upon a fixed part of the lay, This mechanism 0 crates satisfactorilyin the great majority 0 cases, but there are certain. peculiar conditions arising at timesin the practical o oration be cut or parted .when the re lenishmg -mechanism has been withheld from operation. When the shuttle is so'far out of position that the shuttle-feeler is squarely engaged there is no trouble, for then the threadparting'device cannot engage the fillin but sometimes the shuttle is ust for enou out of position to engage the shuttle-feels! and prevent filling replenishment, and as the lay completes its forward movement. the shuttle will be pushed into the box, or the feeler will slide oil the nose of the shuttle. When this occurs the parting. device fwill free, qnently an age and part the filli' g, so that or its object the production of novel inennswhereby he filling end cannot be out ('even if uttle- '7 feelerdoes move past the shuttleinto full rearward position) unless the filling-replenishing mechanism has been brought into action. That'is, it the shuttlefeeler detects improper positioning of the shnttleand', thereby prevents the operation of the re .plenishing-mechanism there can be no openction "of the thread-parting device even Letters Patent.

should it be operetively positioned b a sub- 1 equent movement of thdshuttle-feelien To a; et this resiilt, in the present embodiment of in invention, I provide an actuator for the t read-porter, said actuator being normelly inoperative, and by suitable means the actuator is peratively positionedonly when certain m 1 0 rate toefliect the operation of the replenis in mechanism. If the shuttle is improperly oxe said parts are withheld from cooperation and hence the actuator remains inoperative and the thre'ad-parter cannot be glperated, no matter what happens to the uttle-feeler. The various novel features of my invenwill be fully-described in the subjoined s cification and particularly pointed out in e following claims. t Figure 1 is a transverse section of a portion of a loom provided with automatic filling-replenishin mechanism, and threadparting means, su stantiall. as in the Dre per'patentireferred to, an embodying one form: of my present invention, the view he ingtaken on the line 1-1, Fig. 2, looking 'towz'ird the right. is a top plan view of 'a portion of the apparatus shown in Fig.

thethread-panter, in its normal, inoperative position. Fig. '3 s a detail in plan showing the actuator in its'operative position 'and about t9 act ups the threadeder. Fig, 4 is a detail 'in front elevatioi and artly broken out, of the actuator 1nd ndgacent parts.

Referring tb:Fig. j1 the lay A, filling-replenishing mechanismncomprisingy a fillingieeder or ho transfer-rel f fulcrumed' at f and having :1 depending leg; theslotched dog m" on the vusual. sprin -oontrolled arm m carried by Jaidllgan provided with a laternl lug m; the rock-shaft, d which controls'the operation ofthe replenishing mechanism, the arm (l jaston d rock-shaft and normally depressed by spring Sf, said am engagin emirate end bent rearwardly at its upper end at Yflfto constitute a shnttle-feeler; I a'ndthe finger 11/ carried bye-the support Y fandengagingthe'lng m, image be and are all .snbstantially es showniaridn escribed in the ers or parts are caused; to 00- 1, and clearly illustrating the actuator forriers or bob ms ,6 are held in reserve, theer F in. which the filling-car .a l ugj 30 onl=the swmglng support Y, in

Draper patent're'ferred to and operate as ably beveled at its front end, as at 9.

therein set forth. The arm E supports al thread-catcher, as in said patent, but forming no part of my invention, and the shuttle-feeler carries a thread-parter comprising a fixed cutting blade to, and a movable blade and clamp combined, indicated at a", fulcrumed on the shuttle-feeler, and having at its front end a depending heel 0 provided with a setting pin 0", all as in the patent referred to, the rearward movement of the shuttle-feeler, when replenishment is called for, acting to open the blades by the setting pin c so that the filling-end t, Fig. 3, can enter the notched end of the feeler Y between the blades. When the rock-shaft d is turned to elevate the arm 03, .as will be the case when the running filling is exhausted to a predetermined extent, the shuttle feeler swings rearward and across the mouth of the replenishin shuttle-boxB if the shuttle S is properly oxed therein. At such time the nger it permits the dog m to be swung upward into position to engage the hunter C on the lay, as the latter beats up, to cause filling re lenishment. If the shuttle is imroperly boxed, however, the feeler Y will be engaged and held from its rearward movement and the finger n will hold the do m down out of the hunter path.

fleretofore the heel c of the movable blade c of the thread-parter has been engaged by the lay or a part fixedly secured thereto, so that the thread-parter would be operated inevitably if the shuttle-feeler should slip ofi and part the end of the shuttle, even though improper positioning of the shuttle had prevented replenishment of filling. In my present inventlon I have provided novel and normally inoperative means for actuating the thread-parter, as will be ex lained.

eferring to Fi 4 the hunter C is formed as part of a bracket 1 which is bolted to the front of the lay, said bracket having a shelf-like portion 2 sustaining an upright, fixed pin 3 on which is fulcrumed the sleevehub 4 of an actuator 5 shown as curved to clear the box-plate bolt a. and flattened at its extremity at 6, and adapted to swing toward and from the front of the lay. -The hub 4 has extended from it op osite to the actuator a short, forwardly bent arm 7 which enters and is movable in a recess 8 formed in the hunter, said arm being prefer- Normally the arm 7 is held against a stop lug 10 on the hunter, Fig. 2, by the action of a s Jring 11, Fig. 4, coiled around-the pin 3 an at one end secured thereto, the other end of the spring being attached to the hub 4, whereby the actuator will be held normally in inoperative position, as shown in Fig. 2, with its extremity 6 adjacent. the

cloth being effected b front of the lay, and the beveled end of the arm 7 projected in advance of the lip of the hunter.

The part 6 of the actuator extends across the path of the heel c" of the movable parttioned to cooperate with the hunter C said dog will first engage the projecting beveled end 9 of the arm 7 and will turn the hub 4 on its pivot far enough to swing the actuator forward into operative position, Fig. 3, before the dog actually engages the bunter. Now the part 6 of the actuator will engage the heel c and operate the movable blade 0 as the lay completes its forward beat, and the filling-end t, Fig. 3 will be parted near the shuttle, the cutting near the a cutter Fig. 2, on the temple T, in we 1 known manner. So long as the dog engages the arm 7 the actuator 5 will remain in its operative position, to actuate the thread-parter.

Su pose that replenishment is called for, but t e shuttle is not roperly in the box B. This is detected by tie feeler Y, and the dog m" cannot engage. either the arm 7 of the actuator or the hunter C, so that the.

spring ,11 retains the actuator inoperative. Even should the feeler slip past the shuttle, after preventing replenishment of filling, the thread-parter cannot be operated, for the part 6 of the actuator is in its inoperative position and hence cannot engage the heel of the movable cutting blade 0.

I have shown for convenience 'one form of thread-parting .mechanism, but it will be understood that so far as my invention is concerned other suitable forms may be used provided the construction is such that the same can be actuated bythe operativelypositioned actuator in accordance with my present invention.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is

r 1. An automatic filling-replenishin loom in which the filling is replenished before complete exhaustion havin in combination, a shuttle-feeler, a device mounted thereon to part the spent fillin an actuator for said device mounted on" he la and means to move said actuator relative y to the lay and into operative position only when the fillingr eplenishing mechanism is brought into actron.
